			This is still the only way to submit mgmt frames in case of 10.X firmware. This patch introduces wmi_mgmt_tx queue, because of the fact WMI command can block. This is a problem for ath10k_tx_htt(), since it's called from atomic context. The skb queue and worker are introduced to move the mgmt frame handling out of .tx callback context and not block.
